150/200×100%=75%
75% of 200 miles is 150 miles
In order to write the given number in Scientific Notation we have to move the decimal digit 10 places to the right.
Moving decimal to the right means, the exponent of 10 will be negative when the number is written in scientific notation.
Since, we have to move the decimal by 10 digits, the exponent of 10 will be -10.
Therefore, the number written in scientific notation will be:
Luckily you are not required to use a ruler or be exact- so it just has to be in the range. I would (in pencil or erasable color) divide the line into 4 sections as guide points then determine where each of the sections would go. EX: If it was 4/10 I know it is closer to the 1/2 mark then the 1/4 mark and place the dot.
If you need to, find where the marks would be before simplified-- 3/10's half way guide point isn't 1/2 its 5/10.
Answer:
r
Step-by-step explanation:
The variable r is the dependent variable in the expression.
The value of r will depend on the value of d. The variable d will not affected even if you change the value of r.
The variable r will change depending on the value of d.
So in conclusion, the value of r will only change depending on the value of d.
